Frequently Asked Questions
What package style does this sensor use?
It is housed in a hermetically sealed 4-lead TO-72 style metal can with a locating tab on the rim and a clear top optical window.
How is lead orientation determined on the 4-lead can?
The package includes a metal indexing tab protruding from the rim to provide a physical reference for pin orientation.
There is something deeply satisfying about gold-plated hermetic cans with real glass windows looking down at bare silicon. Pop it into your breadboard or restore a vintage chassis, and put clean analog photon detection back to work.
